Waste management

Building a stronger NDA Group with relentless focus on nuclear clean-up

David Peattie: "Changes to the way we work and manage ourselves will be the most significant since our organisation was created in 2005."

As our Annual Report and Accounts for 2017 to 2018 are published, David Peattie, Chief Executive of the Nuclear Decommissioning Authority, looks back over a year of progress and reflects on the learning that will transform the NDA into a stronger organisation, in the best possible shape to face challenges of the future.

Paratoi’r achos ar gyfer diogelwch Cyfleuster Gwaredu Daearegol

O fewn RWM mae yna is-grwpiau a thimau gwahanol. Dwi’n ffisegydd siartredig, a fy ngwaith i yw dangos na fydd Cyfleuster Gwaredu Daearegol (GDF) yn achosi niwed i bobl na'r amgylchedd. Mae gwaredu daearegol yn cynnwys ynysu a gosod gwastraff ymbelydrol mewn daeargelloedd a thwneli, yn ddwfn o dan ddaear, rhwng 200m a 1000m o dan yr wyneb. Mae hyn yn atal ymbelydredd rhag cyrraedd yr wyneb mewn lefelau a allai achosi niwed. Caiff gwastraff ymbelydrol solet ei becynnu mewn cynwysyddion diogel sydd wedi’u peiriannu, a wneir fel arfer o fetel neu goncrid, a'u gosod mewn ffurfiant creigiau sefydlog, gyda'r cynwysyddion wedi'u hamgylchynu gan glai neu sment. Gelwir hyn yn ddull aml-rwystr.

Making a case for the safety of a Geological Disposal Facility

Lucy Bailey is a chartered physicist working for Radioactive Waste Management, and it’s her job to show that a Geological Disposal Facility (GDF) will not cause any harm to people or the environment. Geological disposal involves isolating and containing radioactive waste in sealed vaults and tunnels deep underground, between 200 m and 1000 m below the surface. This prevents radioactivity from ever reaching the surface in levels that could cause harm.

Being a woman in nuclear: challenging but rewarding

International Women’s Day shed focus on the strengths and achievements of women around the world. And to showcase women in the nuclear industry, Clare Fuller hears from two women: Dorothy Gradden OBE, who started her career more than 20 years ago, and Heather Patterson, who only began working in the industry last October. Together, they highlight the differences in the sector.
